New Features

ConvNeXT Image Classification (By Facebook)

NEW: Introducing ConvNextForImageClassification annotator in Spark NLP. ConvNextForImageClassification can load ConvNeXT models that compete favorably with Transformers in terms of accuracy and scalability, achieving 87.8% ImageNet top-1 accuracy and outperforming Swin Transformers on COCO detection and ADE20K segmentation, while maintaining the simplicity and efficiency of standard ConvNets.

This annotator is compatible with all the models trained/fine-tuned by using ConvNextForImageClassification for PyTorch or TFConvNextForImageClassification for TensorFlow models in HuggingFace

A ConvNet: ImageNet-1K classification results for • ConvNets and ◦ vision Transformers. Each bubble’s area is proportional to FLOPs of a variant in a model family. by Zhuang Liu, Hanzi Mao, Chao-Yuan Wu, Christoph Feichtenhofer, Trevor Darrell, Saining Xie.

BART for NLG, Translation, and Comprehension (By Facebook)

NEW: Introducing BartTransformer annotator in Spark NLP

BartTransformer can load BART models fine-tuned for tasks like summarizations.

This annotator is compatible with all the models trained/fine-tuned by using BartForConditionalGeneration for PyTorch or TFBartForConditionalGeneration for TensorFlow models in HuggingFace

The abstract explains that Bart uses a standard seq2seq/machine translation architecture, similar to BERT’s bidirectional encoder and GPT’s left-to-right decoder. The pretraining task involves randomly shuffling the original sentences and replacing text spans with a single mask token. BART is effective for text generation and comprehension tasks, matching RoBERTa’s performance with similar training resources on GLUE and SQuAD. It also achieves new state-of-the-art results on various summarization, dialogue, and question-answering tasks with gains of up to 6 ROUGE.

The Bart model was proposed in BART: Denoising Sequence-to-Sequence Pre-training for Natural Language Generation, Translation, and Comprehension by Mike Lewis, Yinhan Liu, Naman Goyal, Marjan Ghazvininejad, Abdelrahman Mohamed, Omer Levy, Ves Stoyanov, and Luke Zettlemoyer

Zero-Shot for Text Classification by BERT

NEW: Introducing BertForZeroShotClassification annotator for Zero-Shot NLP Text Classification with Spark NLP. You can use the BertForZeroShotClassification annotator for text classification with your labels!

Zero-Shot Learning (ZSL): Traditionally, ZSL most often referred to a fairly specific type of task: learning a classifier on one set of labels and then evaluating on a different set of labels that the classifier has never seen before. Recently, especially in NLP, it’s been used much more broadly to get a model to do something it wasn’t explicitly trained to do. A well-known example of this is in the GPT-2 paper where the authors evaluate a language model on downstream tasks like machine translation without fine-tuning on these tasks directly.

Let’s see how easy it is to just use any set of labels our trained model has never seen via the setCandidateLabels() param:

zero_shot_classifier = BertForZeroShotClassification \
    .pretrained() \
    .setInputCols(["document", "token"]) \
    .setOutputCol("class") \
    .setCandidateLabels(["urgent", "mobile", "travel", "movie", "music", "sport", "weather", "technology"])
